Hotcoated two boards this afternoon (one long and one short) and as they kicked I saw orangepeel set in. Both are set now and I am looking at a long sanding job ahead of me. Any advice on the best way to tackle the sanding (grit progression etc…) and what caused it to kick this way? Also, do I need to do another hotcoat? Thanks, Magoo

Thanks, Magoo>>> either one of the three things I list here is most likely the problem: 1)moisture; either in your bucket/brush or on your surfaces. 2)air movement; you have a draft,or you are using fans? The air must be dead still when coating(not so important when laminating). 3)overheating; either your resin is to hot of a batch(to much cat.)or your air temp is or both. START,WITH 80 GRIT,I say this because most people can’t handle coarser grits,but if you need to you can start with 50 or 60 GRIT. REMEMBER!!!DON’T OVER SAND AND DON’T SIT IN ONE SPOT FOR TO LONG KEEP THE SANDER MOVING!!!Just come back to the spot when it cools down,it might take a few passes ,but at least you won’t have a burned thru board.GOOD LUCK MAGS!Herb.
What do ya mean by orangepeel?
What do ya mean by orangepeel? If you think of an oranges’ peel it is not smooth. It has a mottled surface. You can determine the quality of an automobiles paint job by the the orangepeel factor as well. Many production shops put out a less than perfect job and then cover it up by shooting a clearcoat over it. But you can still see the peel if you look. Thanks for the quick response Herb, I can always count on you! I’m gonna start with the 80… Magoo

I live in Florida and the temps can get pretty hot. It’s perfect temp right now, around 70’s to 80’s. I don’t have a climate controlled environment in which to do my boards so I have to settle on the garage… Thanks, Jeff
